Any new News on extended batteries?

I know the update gave us a little more juice for the moment. I was just wondering if anyone has found a Samsung Moment specific extended battery. If not what has been the result of the portable chargers for backup. I need an option which will allow me to fly from LA to NY, run around the city and still have juice to make calls if needed. So I need a 2000+ alternative.

Mugen Power manufactures a 2600mAh battery that is badged for the instinct HD that does fit the Moment(they use the same stock battery), however, as of yet, there is no replacement battery door to go with it.
